Phoenix WinFlash for UEFI
Manufacturers like Lenovo have recently used EFI technology from Phoenix.
The flashing tools:
WinFlash.exe for windows
and
PFlash.exe for DOS
Both of them are using command lines:
Phoenix WinFlash for UEFI Command Options
Code:
Phoenix WinFlash for UEFI Command Options
This section lists WinFlash command options and parameters.
Syntax
WINFLASH [options] [romfile] [@rspfile]
romfile The new BIOS p_w_picpath name, eg: BIOS.FD
@rspfile The response file (PFLASH.RSP by default) contains all command parameters in text format.
/? or /help or /h Displays help screen
/all Flash the entire p_w_picpath including the descriptor region

Tips:
If using a moded Bios the flash fails, open WINFLASH.LOG
if you see the following errors, a hack of environment.dll is needed.
Code:
[0403/001701:INFO:utils.cpp(29)] p_w_picpathDigest fail!
[0403/001701:INFO:utils.cpp(29)]
Fail to authenticate p_w_picpath!
[0403/001701:INFO:utils.cpp(29)] Fail to authenticate p_w_picpath!
Fail: UNSUPPORTED!
Verified for WinFlash for UEFI versions 1.4.64.0 to 1.4.83.0
in environment.dll
replace
68 01 00 83 C4 0C 85 C0 74 15
by
68 01 00 83 C4 0C 85 C0 EB 15
to suppress "p_w_picpathDigest fail!" error
or
83 C4 14 89 45 E0 83 7D E0 00 74 31
by
83 C4 14 89 45 E0 83 7D E0 00 EB 31
to suppress "Fail to authenticate p_w_picpath!" error
(this second hack is not necessary if first is applied)
SLIC insertion/replacement
These tools allow the marker and pubkey insertion by command line:
/slp:filename Replace SLP marker (bin size=182 octets)
/spu:filename Replace SLP pubkey (bin size=156 octets)
/ss Use current SLP
BIOS recovery instructions
are explained in a packard bell document, but the needed files are not yet available on the net.
Hope these informations will help modders
